ABSTRACT

An automatic washing machine which can compress and decompress clothes during washing process comprises an enclosed support frame, a water tub mounted in the support frame, a cylindrical basket rotatably mounted in the water tub, a central shaft rotatably mounted in the cylindrical basket, variable speed drive motors connected to central shaft and cylindrical basket, shaft fins projecting radially outward from the central shaft and basket fins projecting radially inward towards the central shaft interposed between each other and a control panel equipped to rotate the interposed fins of the shaft and cylindrical basket independently or together at uniform or different speeds in the same or different directions in order to compress, decompress, agitate, hold and spin water soaked clothes to wash, rinse and dehydrate.

TECHNICAL FIELD

The present invention relates in general to laundry washing machineswhich automatically wash, rinse, and dehydrate clothes by agitating,oscillating and spinning water soaked clothes.

Particularly this invention relates to laundry washing machines whichcompress and decompress clothes in addition to agitating, oscillatingand spinning them in order to increase the efficiency and speed ofwashing, rinsing and dehydrating process saving time, water anddetergent.

BACKGROUND

Presently laundry is washed manually by hand or automatically by toploading or front loading washing machines. In manual washing, clothesoaked in detergent—water solution is beaten, squeezed, twisted, wringedand agitated in water by hand. The compression of clothes caused bythese actions dilates the pores of fabric squeezing out water and soapsuds through the pores to remove even embedded dirt efficiently andquickly. In machine washing the clothes are only agitated vigorously bythe oscillation of clothes soaked in detergent-water solution by anoscillator basket with or without the aid of agitator plates or axialshaft with fins.

After washing dehydrating is done in machines by spinning the clothes atvery high speed. Machines generate severe vibration and noise whilespinning at high speeds on account of imbalance caused by the unevendistribution and unrestricted movement of clothes in the basket.

In washing machines having only vertical or horizontal oscillators andagitators, improved efficiency can be achieved by incorporating amechanism which can compress clothes in addition to agitating andoscillating them.

In washing machines dehydrating clothes by high speed spinning severevibration and noise generated due to imbalance can be minimized byincorporating a mechanism to hold clothes in steady, compressed andbalanced state.

OBJECTS OF THE INVENTION

The primary object of the invention is to impart to automatic toploading and front loading laundry washing machines a capability forcompressing water soaked clothes in addition to agitating and spinningthem in order to wash, rinse and dehydrate clothes more efficientlysaving time, water and detergent.

Another object of this invention is to impart to automatic top loadingand front loading laundry washing machines a capability to hold clothesin steady, compressed, evenly distributed state during spinning processin order to minimize imbalance, vibration and noise in the machine.

The said extension tube ‘B’ (FIG. 1) seats bearings ‘X’(FIG. 1) and water seals ‘Q’ (FIG. 1) inside it.

Inside the said water tub ‘C’ (FIG. 1) a perforated cylindrical basket‘F’ (FIG. 1) is disposed vertically, concentrically and rotatably. Thecylindrical basket ‘F’ (FIG. 1) has a mouth at it's top side wide enoughto load and unload clothes. At the bottom side it has a hole openinginto an attached extension tube ‘V’ (FIG. 1) protruding downward intothe extension tube ‘B’ (FIG. 1) of the said water tub. There arebearings ‘X’ (FIG. 1) and seals ‘Q’ (FIG. 1) seated inside the extensiontube of the cylindrical basket ‘F’ (FIG. 1) also. The extension tube ‘V’(FIG. 1) of the cylindrical basket is engaged by the said bearings ‘X’(FIG. 1) in the extension tube ‘B’ (FIG. 1) of the water tub which holdit concentrically, vertically and rotatably. The-said water seals ‘Q’(FIG. 1) in the extension tube of the water tub 'C prevent the leakageof water from the water tub. A pair of perforated fins ‘P1 and P2’(FIGS. 1, 2 & 3) protrude inward from the diametrically opposite insidewalls of the cylindrical basket towards the center of the basket ‘F’(FIGS. 1,2 & 3).

A central shaft ‘G’ (FIG. 1) is disposed in the said cylindrical basket‘F’ (FIG. 1) vertically, concentrically and rotatably. The lower portionof the shaft ‘G’ (FIG. 1) protrudes into the extension tube ‘V’ (FIG. 1)of the cylindrical basket. The bearings inside the extension tube 'V(FIG. 1) is engaged to the shaft extension ‘N’ (FIG. 1) and hold itconcentrically, vertically and rotatably. The seals ‘Q’ (FIG. 1) insidethe extension tube ‘V’ (FIG. 1) of the cylindrical basket prevent theleakage of the water from the cylindrical basket ‘F’ (FIG. 1). A pair offins ‘H1 and H2’ (FIGS. 1, 4 & 5) protrude outward from diametricallyopposite sides of the shaft ‘G’ (FIG. 1) radially towards the walls ofthe cylindrical basket ‘F’(FIG. 1). The fins of the shaft ‘H1 and H2’and the fins of the basket ‘P1 and P2’ interpose between each other(FIG. 6).

The lower ends of shaft extension ‘N’ (FIG. 1) and the extension tube‘V’ (FIG. 1) of cylindrical basket ‘F’ are connected to drive means ‘K1and K2’ (FIG. 1) through transmission means ‘J1 and J2’ (FIG. 1) whichcan rotate the shaft ‘G5’ (FIG. 1) and the basket ‘F’ (FIG. 1) withtheir fins individually or together at uniform or different speeds inthe same or opposite direction for any period of time.

The electrical equipment in the machine are connected to power sourceand a control panel on the support frame ‘A’. The control panel isequipped with programs that operate and control the rotation of shaftand basket with their fins which agitate, compress, decompress and spinclothes soaked in water inside the basket to wash, rinse and dehydratethem.

The present disclosure also discloses one of the many programs forworking of the top loading embodiment of the machine as described belowwith the help of drawings. The shutter (L FIG. 1) is removed to open themachine. Shaft fins ‘H1 and H2’ (FIGS. 4 & 5) interposed between basketfins P1 & P2 (FIGS. 2, 3 and 6) are rotated and positioned close to thebasket fins to form two large vacant horizontal chambers ‘S1 and S2’(FIG. 6) opposite to each other. Clothes to be washed is divided intoapproximately equal lots and loaded into the two large chambers, S1 andS2 (FIG. 7). Detergent is added. The cylindrical basket ‘F’ (FIG. 1) andwater tub ‘C’ (FIG. 1) are filled with water through the inlet ‘D’(FIG. 1) to a level required to soak and immerse the clothes in water.The drive motors ‘K1 and K2’ (FIG. 1) are started to rotate the shaft‘G’ with fins H1 and H2 (FIGS. 4 & 5) and cloths basket ‘F’ with fins P1and P2 (FIGS. 2 & 3) through transmission gears J1 and J2 (FIG. 1).

The speed of rotation of the shaft fins is greater than the speed ofrotation of basket fins. The direction of rotation of both shaft finsand basket fins is anticlockwise. As a result the shaft fins approachthe basket fins sweeping the water soaked, clothes to the basket finsand compressing them against the basket fins and squeezing them “S3” and“S4” (FIGS. 8 & 12). After squeezing the clothes the basket and basketfins are made to rotate faster than the shaft fins in the sameanticlockwise direction. As a result the basket fins move away from theshaft fins decompressing the clothes (FIGS. 13 to 15). Repeatedcompressing and decompressing action by changing the speed or changingthe direction of rotation not only agitates but also squeezes to removedirt from the clothes.

On account of simultaneous squeezing, de squeezing and spinning motionsthe relative positions of fins and their relative angles continuouslychange to alter the direction and force of flow of water and clothes inthe basket. The resultant vigorous agitation of water and clothes in thebasket adds to the speed and efficiency of washing and rinsing. Theprocess is repeated to complete the wash. Thereafter the fins arebrought closer to hold the clothes in compressed state. The rotation ofthe shaft and basket is stopped. The extracted water is drained throughoutlet “E” (FIG. 1) and fresh water is filled through inlet “D” (FIG.1). The clothes are rinsed with an operation similar to the washingoperation which is repeated with change of water to complete rinsing. Atthe end of rinsing the fins are again brought close to each other tohold steady the clothes in compressed state. The rotation of the machineis stopped. The basket is drained of extracted water holding the clothesin compressed state between the fins in balancing position. Then theshaft and basket are rotated at uniform high speed in the same directionto dehydrate the clothes by centrifugal force. The squeezed out water isdrained out. The washed, rinsed and dehydrated clothes are then driedand used.

Referring to FIGS. 17 to 30 a front loading embodiment of an automaticwashing machine which compresses, decompresses, agitates, oscillates andspins water soaked clothes to wash, rinse and dehydrate is describedbelow. The disclosed invention comprises an outer support frame (A1 FIG.17). The support frame (A1) has a water inlet (D1 FIG. 17), a wateroutlet (E1 FIG. 17) at it's sides, and control panel with powerconnections. At it's front side it has a door with a shutter (L1 FIG.17).

The water tub (CI, FIG. 17) has a wide mouthat it's front side and connections to water inlet (D1, FIG. 17) forfresh water and water outlet (E1, FIG. 17) for used water connected topumps. The rear side has a hole at it's center opening into an‘extension tube’ (B1, FIG. 17) protruding backward into the rear portionof the support frame (A1, FIG. 17). The said extension tube (B1, FIG.17) seats bearings (X1, FIG. 17) and water seals (Q1, FIG. 17) insideit.

Inside the said water tub (C1, FIG. 17) a perforated cylindrical basket(F1, FIG. 17) is disposed horizontally, concentrically and rotatably.The cylindrical basket (F1, FIG. 17) has a mouth at it's front side wideenough to load and unload clothes. At the rear side it has a holeopening into an attached extension tube (V1, FIG. 17) protrudingbackward into the extension tube (B1, FIG. 17) of the said water tub.There are bearings (X1, FIG. 17) and seals (Q1, FIG. 17) seated insidethe extension tube of the cylindrical basket (F1, FIG. 17) also. Theextension tube (V1, FIG. 17) of the cylindrical basket is engaged by thesaid bearings (X1, FIG. 17) in the extension tube (B1, FIG. 17) of thewater tub which hold it concentrically, horizontally and rotatably. Thesaid water seals (Q1, FIG. 17) in the extension tube of water tub (C1)prevent the leakage of water from the water tub. A pair of perforatedfins (P3 & P4, FIGS. 17, 18 & 19) protrude inward from the diametricallyopposite inside walls of the cylindrical basket towards the center ofthe basket (F1, FIG. 17).

A central shaft (G1, FIG. 17) is disposed in the said cylindrical basket(F1, FIG. 17) horizontally, concentrically and rotatably. The rearportion of the shaft (G1, FIG. 17) protrudes into the inner extensiontube (V1, FIG. 17) of the cylindrical basket. The bearings inside theextension tube (V1, FIG. 17) is engaged to the shaft extension (N1, FIG.17) and hold it concentrically, horizontally and rotatably. The seals(Q1, FIG. 17) inside the extension tube (V1, FIG. 17) of the cylindricalbasket prevent the leakage of the water from the cylindrical basket (F1,FIG. 17). A pair of fins (H3 & H4, (FIGS. 17, 20 & 21) protrude outwardfrom diametrically opposite sides of the shaft (G1, FIGS. 20 & 21)radially towards the walls of the cylindrical basket (F1, FIG. 22). Thefins of the shaft (H3, H4) and the fins of the basket (P3 & P4)interpose between each other (FIG. 22).

The rear ends of shaft extension (N1, FIG. 17) and the extension tube(VI, FIG. 17) of cylindrical basket (F1) are connected to drive means(K3 & 4, FIG. 17) through transmission means (J3, J4, FIG. 17) which canrotate the shaft (G1, FIG. 17) and the basket (F1, FIG. 17) with theirfins individually or together at uniform or different speeds in the sameor opposite direction for any period of time.

The electrical equipment in the machine are connected to power sourceand a control panel on the support frame (A1). The control panel isequipped with programs that operate and control the rotation of shaftand basket with their fins which agitate, compress, decompress and spinclothes soaked in water inside the basket to wash, rinse and dehydratethem.

One of the many programs for working of the front loading embodiment ofthe machine is described below with the help of drawings. The shutter(L1, FIG. 17) is removed to open the machine. Shaft fins (H3 & H4, FIGS.20 & 21) interposed between basket fins (P3 & P4, FIGS. 17,18 & 19) arerotated and positioned close to the basket fins to form two large vacantvertical chambers (S3 & S4, FIG. 22) opposite to each other. Clothes tobe washed is divided into approximately equal lots and loaded into thetwo large chambers (S3 & S4, FIG. 23). Detergent is added. Thecylindrical basket (F1, FIG. 17) and water tub (C1, FIG. 17) are filledwith water through the inlet (D1, FIG. 17) to a level required to soakand immerse the clothes in water. The drive motors (K3 & K4, FIG. 17)are started to rotate the shaft (G1, FIGS. 17, 20 & 21) with fins (H3,H4) and cylindrical basket (F1) with fins (P3 & P4, FIGS. 17, 18 & 19)through transmission gears (J3 & J4, FIG. 17).

The shaft fins and basket fins which are positioned close and parallelto each other as in FIGS. 22 & 25 are rotated together at the same speedthrough 180° in anticlockwise direction agitating the clothes in waterand shifting the position of clothes from one chamber to the other (S3,S4) in decompressed state (FIG. 26). Next the fins are rotated back tooriginal position rotating thein together in clockwise directionagitating the clothes in water and shifting the position of clothes backto their original chambers (S3, S4) in decompressed state (FIG. 27). Theprocess is repeated as many times as required.

Next the shaft fins (H3 & H4, FIG. 28) are rotated through 135° inanticlockwise direction while the basket fins (P3, P4) are held steadythereby compressing the clothes between the basket fins and shaft finsfrom one half occupied space to one quarter occupied space.

Thereafter the shaft fins are rotated back 135° clockwise close tobasket fins restoring the clothes to decompressed state (FIG. 29). Nextthe shaft fins (H3, H4) are held steady and basket fins (P3, P4) arerotated 135° clockwise to compress the clothes against the shaft fins.

The cycle of movements is reversed repeatedly to agitate, compress anddecompress intermittently the clothes in water to squeeze out dirtspeedily and efficiently.

Repeated compressing and decompressing action by changing the speed orchanging the direction of rotation not only agitates but also squeezesto remove dirt from the clothes.

On account of simultaneous squeezing, de squeezing and spinning motionsthe relative positions of fins and their relative angles continuouslychange to alter the direction and force of flow of water and clothes inthe basket. The resultant vigorous agitation of water and clothes in thebasket adds to the speed and efficiency of washing and rinsing. Theprocess is repeated to complete the wash. There after the fins arebrought closer to hold the clothes in compressed state. The rotation ofthe shaft and basket is stopped. The extracted water is drained throughoutlet (E1, FIG. 17) and fresh water is filled through inlet (D1, FIG.17). The clothes are rinsed with an operation similar to the washingoperation which is repeated with change of water to complete rinsing. Atthe end of rinsing the fins are again brought close to each other tohold steady the clothes in compressed state. The rotation of the machineis stopped. The basket is drained of extracted water holding the clothesin compressed state between the fins in balancing position. Then theshaft and basket are rotated at uniform high speed in the same directionto dehydrate the clothes by centrifugal force. The squeezed out water isdrained out. The washed, rinsed and dehydrated clothes are then driedand used.

The operations described above in top loading and front loadingembodiment of the disclosure are automated, computerized and programmedby known electrical and electronic technology and necessary addition ofknown components.

The many variable factors available in the invention like independentrotation of multiple components, variable speed of components, variabledirection of rotation, variable pressure of compression, variable anglesof fins and variable periods of rotation offer wide scope forprogramming it's operations to suit wide range of needs of laundrywashing.
